Message-ID: <20241216173514.495638-1-uwu@icenowy.me> Date: Tue, 17 Dec 2024 01:35:14 +0800 From: Icenowy Zheng <uwu@...nowy.me> To: Thomas Bogendoerfer <tsbogend@...ha.franken.de>, Huacai Chen <chenhuacai@...nel.org>, Jiaxun Yang <jiaxun.yang@...goat.com> Cc: linux-mips@...r.kernel.org, linux-kernel@...r.kernel.org, Baoquan He <bhe@...hat.com>, Vivek Goyal <vgoyal@...hat.com>, Dave Young <dyoung@...hat.com>, kexec@...ts.infradead.org, Icenowy Zheng <uwu@...nowy.me> Subject: [PATCH] mips: disable CRASH_DUMP by default On MIPS, the space of a crash dump kernel needs to be manually specified by both the debugee and the crash dump kernel PHYSICAL_START config option, and the default PHYSICAL_START config will make the kernel load quite higher, which isn't acceptable when using as a daily use kernel (and will even confuse some naive Loongson-3 bootloaders). So I don't think a MIPS kernel should be built as a crash dump kernel by default, therefore this patch disables selecting CRASH_DUMP by default.
